Problems solved by technology

The commonly used cotton fiber printing and dyeing method usually needs to scouring the cotton fiber before printing and dyeing to remove impurities such as pectin wax and protein in the cotton fiber, which reduces the strength of the cotton fiber and affects the performance of cotton textiles. There is also the common problem of poor color fastness and easy fading. Because infants are used to licking and sucking items, once the dye is ingested into the body by mouth, it will have adverse effects on infants.

Embodiment 1

[0022] A printing and dyeing method of cotton fiber for infants and young children, comprising the following steps:

[0023] (1) Pretreatment: The cotton fiber was treated in a NaOH solution with a concentration of 15g / L at a temperature of 85 °C and a bath ratio of 1:20 for 2 hours, and then rinsed and washed in a hydrogen peroxide solution with a concentration of 5g / L. Under the conditions of pH 8, temperature 50°C, and bath ratio of 1:20, the medium was treated for 0.5h, then washed with water and dried to obtain pretreated cotton fibers;

[0024] (2) Dyeing: placing the pretreated cotton fiber obtained in step (1) in a natural dye, and dyeing for 1 hour under the conditions of pH 5.5, temperature 70°C, and bath ratio 1:20;

[0025] (3) vacuum pressurization: placing the dyed cotton fibers in step (2) in a vacuum pressurizing tank, first vacuuming to a degree of vacuum of 0.06MPa, holding for 5min and then pressurizing to 0.3MPa, and maintaining the pressure for 1h;

Abstract

The invention belongs to the technical field of textile printing and dyeing, and discloses a printing and dyeing method for cotton fibers for infants and young children. ) dyeing: carry out dyeing treatment with natural dyeing agent; (3) vacuum pressing: carry out vacuum pressing treatment to the cotton fiber after dyeing; (4) color fixing: carry out color fixing treatment to cotton fiber after vacuum pressing treatment; (5) Impregnation modification: Impregnation and modification of the fixed cotton fibers are carried out with collagen-simulated body fluid composite impregnation solution, and then rinsed and dried. The cotton fiber printing and dyeing method of the invention can not only maintain the strength of the cotton fiber, improve the durability and comfort of the fabric, but also make the cotton fiber have high dyeing fastness, thereby effectively improving the dyeing and wearing performance of the cotton fiber for infants and young children.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a printing and dyeing method of cotton fibers for infants and young children. Background technique [0002] Cotton fiber has good moisture absorption, air permeability, softness, hygiene and wearing comfort, and is welcomed by consumers. In order to achieve the purpose of aesthetics and other uses, it is often necessary to print and dye cotton fibers before they are made into cotton textiles. Infant textiles mainly include outerwear, underwear, towels, etc. Since infants and young children have relatively weak resistance and delicate skin, they are more sensitive to external stimuli, so they have special requirements for the textiles used. The currently commonly used cotton fiber printing and dyeing method usually requires scouring the cotton fiber before printing and dyeing to remove impurities such as pectin, wax and protein in the cotton fiber, which reduc...
